The default VLAN ID for untagged traffic on most switches is VLAN 1.

Most switches have VLAN 1 as the default VLAN, which is used for management and control traffic.

The depletion region in a semiconductor diode is a region of low conductivity where no free charge carriers are present due to recombination.

A latching switch remains in its last position until manually changed, while a momentary switch only stays on while pressed.

The duty cycle in astable mode depends on the resistor and capacitor values used in the circuit.

A 'shift left' operation on a binary number effectively multiplies the number by 2.

A left shift operation on a binary number effectively multiplies the number by 2.

Adding a capacitor in parallel with a resistor affects the time constant of the circuit, as it introduces a reactive component.

A FET can control the load current based on the gate voltage applied, allowing for variable control in series circuits.

Increasing capacitance in an RC circuit increases the time constant (τ = R*C), leading to a slower time response.

Connecting a diode in parallel with a resistor allows current to bypass the resistor when the diode is forward-biased.

Enabling PortFast allows a switch port to transition to the forwarding state immediately, bypassing the listening and learning states.

Increasing capacitance in an RC circuit results in a slower response due to a larger time constant.

According to Ohm's Law, if resistance increases while voltage remains constant, the current will decrease.

Increasing the feedback resistor (Rf) in a non-inverting op-amp configuration increases the gain.

As the frequency of an AC signal increases, a capacitor allows more current to pass due to its decreasing reactance.

Increasing the frequency of an AC signal decreases the reverse recovery time of a diode, allowing it to switch faster.

The reactance of a capacitor decreases with increasing frequency, allowing more AC current to pass.

Increasing the gate voltage in an n-channel FET enhances the channel conductivity, thus increasing the current.

Increasing the load resistance generally decreases the power delivered to the load, according to Ohm's law.

Increasing the number of turns in an inductor increases its inductance.

Increasing the number of turns in the primary winding increases the output voltage in a step-up transformer.

Increasing the resistance in an RL circuit decreases the current according to Ohm's law.

Increasing the resistance in the timing circuit of an astable 555 timer decreases the frequency of the output waveform.

Increasing Rf in a non-inverting op-amp configuration increases the output voltage.

Increasing the voltage across a capacitor increases the amount of charge stored, as capacitance is constant.

Negative feedback decreases gain and improves stability in op-amp circuits, leading to better performance.

As temperature increases, the resistance of semiconductors typically decreases due to increased carrier mobility.

The capacitance of ceramic capacitors typically decreases with increasing temperature.

An ideal transformer has an efficiency of 100%, meaning no energy is lost.
